Adjustments and operations
Shanks depth adjustment
The working depth must be adjusted regarding the depth of the compacted layer on
the soil.
To do so, use devices such as penetrometers or, to simplify, open trenches with the
aid of any sharp tool and find the depth of the compacted layer.
Besides the depth, it is also necessary to know the thickness of this layer.
It is necessary to know these points to adjust the working depth properly and avoid
wastes, such as: high skidding index, high use of fuel, greater wear on the tires and low
income.
Another factor to pay attention is the soil humidity rate. An ideal soil is a friable one
(one that breaks or crumbles with easiness).
The humidity factor is easy to understand, because when working with high humidity,
the shanks will pass over the soil but not penetrate. If the soil is completely dry, the job will
remove great clods, which are hard to destroy afterwards.
